Answer:

principle = 2000

rate =20%

Amount= 83100

No. of compounds per year = n = 12

A=P(1+r/n)nt

83100=2000(1+20/100×12)12

83100=2000(1+1/60)12

83100=2000(1/1+1/60)12

83100=2000(60+1/60)12

83100=2000(61/60)12

83100/12=2000×61/60

83100/12=200×61/6

83100/12=200(61/6)

83100/12×200=61/6

831/24=61/6

Now cross multiply

831×6=24×61

4986=1464

now divide

3.4057.....
